ABSTRACT:
A plastic cased metal headed ammunition casing for high powered rifle and cannon cartridges is described in which the plastic case has a pressure regulating baffle or wall in the forward and thereof to regulate and control the development of chamber pressure and directs pressure into a space around the bore of the projectile prior to movement of the projectile. The cartridge is charged with a given charge of powder and the cap or head securely fastened to the rearward portion of the plastic casing. An expandable sleeve may be used to stabilize the head-casing interfit. The head provides sufficient resistance to the residual pressure after firing so that the cartridge can be used in rapid fire automatic weapons.
